First, consider the parametric association (Pearson's r) between age and bouts of physical activity per week. I've calculated a nonparametric Spearman's rank correlation for the same data (see table below) using ranks instead of actual values

q.Do you come to a similar conclusion when you use a parametric or nonparametric test? (This means, do you accept the same hypothesis either way) Why do you think this is?

When would it be inappropriate to report the Pearson's correlation? When would it be inappropriate to report a Spearman's correlation
